  Examples of the present invention will be described below.

  An embodiment of the present invention will be described with reference to the drawings. First, FIG. 1 is a perspective view showing an entire image of a sofa 1 as an embodiment of furniture having a lighting function in the present invention. The sofa 1 is a cushion body 2 composed of eight flexible balloons 2a to 2h formed of a translucent translucent polyurethane resin material, which is formed as a bag body capable of sealing gas (air) inside. And a base 4 disposed below the cushion body 2.

  As shown in FIGS. 1 and 2, the cushion main body 2 in the present embodiment has eight balloons 2 a to 2 h that are independently formed in a horizontally long substantially rectangular parallelepiped shape and are arranged side by side on the base 4 without gaps. Each balloon is arranged so that the height gradually decreases from the center in FIG. 2 toward the left and right sides. Each of these balloons 2a to 2h is fitted in an annular cylinder 6 made of a transparent acrylic resin material fixed on the upper surface of the base 4, and is arranged so as not to be displaced. A seating area for the user is formed on the upper surface of ˜2h.

  The base 4 has a cylindrical shape with a hollow interior, and the base 4 corresponds to the air chambers R of the balloons 2a to 2h as shown in the schematic structural diagram of FIG. And a plurality of LED modules 3a to 3h composed of a plurality of LEDs 3 as irradiation means for irradiating the air chamber R of the corresponding balloon from below to above, and the air chamber R of each balloon 2a to 2h. When a change occurs in the air pressure sensor 5 as a plurality of pressure detecting means which are arranged correspondingly and detect the pressure of the corresponding air chamber R, and the pressure detected by the air pressure sensor 5 changes, the pressure changes. A control board 11 provided with a control unit 10 as an irradiation control means for performing control to change the light quantity of the LED 3 of the LED module (3a to 3h) corresponding to the air chamber R is disposed.

  As shown in FIG. 3, the LED modules 3 a to 3 h and the air pressure sensor 5 are respectively arranged corresponding to the balloons 2 a to 2 h in the base 4, and the LEDs 3 of the LED modules 3 a to 3 h are It arrange | positions upwards so that irradiation is possible toward the upper balloon (2a-2h) from the inside of the stand | base 4. Although the upper surface of the base 4 is not particularly illustrated, it is formed of a transparent plate (for example, a transparent synthetic resin plate or a glass plate), and the irradiation light from these LEDs 3 passes upward through the transparent plate. The arranged balloons 2a to 2h are irradiated. By irradiating the balloons 2a to 2h with the irradiation light from the LED 3, the balloons 2a to 2h themselves appear to emit light due to the irregular reflection action by the translucent polyurethane resin material constituting the balloons 2a to 2h. It will be.

  The air chamber R corresponding to the detection portion of each air pressure sensor 5 is communicated via a communication pipe (not shown), and the air pressure inside the air chamber R is detected by the gas flowing out from the air chamber R via the communication pipe. It has come to be. In this embodiment, air (gas) is injected into the air chamber R, but a liquid may be injected.

  Next, the configuration of the sofa 1 according to the present embodiment will be described with reference to the block diagram shown in FIG. 4. The sofa 1 according to the present embodiment includes a plurality of balloons 2 a to 2 h constituting the cushion body 2 and a balloon 2. The air pressure sensor 5 for detecting the air pressure inside the air chamber R, LED modules 3a to 3h composed of a plurality of LEDs 3 for irradiating the corresponding balloon 2 from below, the LED modules 3a to 3h and the air pressure sensor 5 are I / O modules. And a control board 11 provided with a control unit 10 for controlling these units.

  Next, the operation of the sofa 1 as the present embodiment will be described with reference to FIG.

  When it is detected that any of the balloons 2a to 2h has been compressed and the air pressure inside the air chamber R has increased to a predetermined reference value, the control unit 10 detects that the air pressure has reached the predetermined reference value. The LED 3 of the LED modules 3a to 3h corresponding to 2h is turned on with a predetermined light color (blue in this embodiment), and if the air pressure further increases, the light amount of the LED 3 increases in accordance with the increase of the air pressure. If the air pressure decreases, the light amount of the LED 3 is reduced according to the reduction of the air pressure, and the LED 3 is turned off when the air pressure falls below the predetermined reference value.

  In the present embodiment, the control unit 10 lights up the LED 3 with a predetermined amount of light corresponding to the range of pressure detected by each air pressure sensor 5. Accordingly, the light amount of the LED 3 increases or decreases in a stepwise manner.

  Specifically, for example, as shown in FIG. 5, when the user sits on the seating portion on the upper surface of the cushion body 2, the vicinity of the center position of the upper surface seating portion of the cushion body 2 is pressed downward. Then, the LED modules 3d and 3e corresponding to the pressed balloons 2d and 2e near the center are turned on with a light amount corresponding to the pressure detected by the corresponding air pressure sensor 5.

  Here, no force is directly applied to the balloons 2c and 2f arranged adjacent to the central balloons 2d and 2e, but the adjacent balloons 2d and 2e are deformed so as to expand in the lateral direction. Since the air pressure in the air chamber R of the balloons 2c and 2f also increases, the LED modules 3c and 3f corresponding to the balloons 2c and 2f light up with a light amount corresponding to the pressure detected by the corresponding air pressure sensor 5. Is done.

  Further, the balloons 2b and 2g adjacent to the balloons 2c and 2f are also pressed by the balloons 2c and 2f deformed so as to expand in the lateral direction, so that the LED 3 of the LED modules 3b and 3g corresponding thereto also have corresponding air pressure sensors. 5 is turned on with a light amount corresponding to the pressure detected in step 5.

  In FIG. 5, the balloon with the higher density of oblique lines indicates that the light quantity of the LED 3 is higher. As indicated by the arrow in the figure, when a force is applied from the outside only near the center, the force is reduced. The central part directly added is brightest, and gradually darkens toward the periphery.

  As described above, in the sofa 1 according to the present embodiment, when the cushion body 2 is partially pressed by, for example, a person sitting on the cushion body 2 or lying down, the pressure changes due to the pressing. The irradiation control of the LEDs 3 of the LED modules 3a to 3h corresponding to the air chambers R of the generated balloons 2a to 2h is performed. In other words, the amount of irradiation light of the cushion body 2 partially changes (rises or decreases) following the use position of the user, so that not only the vicinity of the user always becomes bright, but also the irradiation according to the use situation of the user. Changing the amount of light enhances the interior decoration effect.

  Further, the control unit 10 according to the present embodiment changes the light amount of the LED 3 for the period (speed) until the air pressure of the predetermined air chamber R increases or decreases from the first value to the second value. Control is performed to slow down the period (speed) of increasing or decreasing from the light amount corresponding to the first value to the light amount corresponding to the second value of the air pressure. Specifically, for example, when it takes 500 ms for the air pressure of the predetermined air chamber R to rise from the first value to the second value, the light amount of the LED 3 corresponds to the light amount corresponding to the first value of the air pressure. The time taken to increase the light amount corresponding to the second value of the air pressure is, for example, 1 second. Thereby, since the change of light becomes dull compared with the change of air pressure and the reaction of light becomes soft, the cushioning property of the cushion body 2 made of air can be visually expressed by the effect of light.

  Further, when the air pressure in the air chamber R is increased, the period (speed) for changing the light quantity of the LED 3 is made faster. Specifically, for example, when it takes 500 ms for the air pressure of the predetermined air chamber R to rise from the first value to the second value, the light amount of the LED 3 corresponds to the light amount corresponding to the first value of the air pressure. The time for increasing the air pressure to the light amount corresponding to the second value of the air pressure is 1 second, while the time of 500 ms is required until the air pressure of the predetermined air chamber R decreases from the second value to the first value. When necessary, the time for reducing the light amount of the LED 3 from the light amount corresponding to the second value of the air pressure to the light amount corresponding to the first value of the air pressure is 1.5 seconds. Thereby, the change of light can be made dull without feeling stress.

  In addition, although irradiation control of LED3 by the control part 10 in a present Example is control of light quantity (dimming), the light quantity of LED3 is reduced by the air pressure of the air chamber R rising, for example contrary to an Example. The light amount of the LED 3 may be increased by lowering the air pressure of the air chamber R.

  Moreover, the irradiation control of LED3 by the control part 10 is not limited only to light quantity control (dimming), For example, according to the change of the air pressure of the air chamber R, irradiation modes, such as colored light, lighting, blinking, etc. Control may be performed. Specifically, control is performed so that all LEDs 3 are lit at normal time, and the irradiation light color of the LED 3 corresponding to the air chamber R in which the air pressure has changed is changed in gradation from blue to red, for example. It may be.

  Further, the LED 3 as the irradiation means in the present embodiment is provided in the base 4 that is separable from the cushion main body 2 disposed below the cushion main body 2. Therefore, the LED 3 can be easily replaced, maintained, and the like.

  In the present embodiment, the LED 3 as the irradiation means is disposed below the cushion body 2, but the present invention is not limited to this. For example, the LED 3 is disposed inside the air chamber R of the cushion body 2. You may arrange in. Moreover, although LED was applied as an example of an irradiation means, you may apply a lamp | ramp etc.

  Although the embodiments of the present invention have been described with reference to the drawings, the specific configuration is not limited to these embodiments, and modifications and additions within the scope of the present invention are included in the present invention. It is.

  For example, in the above embodiment, the sofa 1 is applied as an example of furniture, but the present invention is not limited to this, and the present invention may be applied to a chair, a bed, or the like. The shape of the sofa 1 is not limited to the shape described in the above embodiment.

  Moreover, although the cushion main body 2 in the said Example was comprised by the some balloon 2a-2h each formed independently, by the one balloon by which the internal chamber R was divided into plurality by the partition wall It may be configured.

  Moreover, in the sofa 1 in the said Example, although one control part 10 performed irradiation control of all LED3 corresponding to several balloon 2a-2h, for example, each balloon 2a-2h Control units that control the corresponding LED 3 and air pressure sensor 5 may be electrically connected, and the control units may exchange information regarding pressure and irradiation to control irradiation of each LED module.
